Answer:
first explain what you need help with specifically then maybe people can help, to bland of a question
If the sum of their lengths is 5,520 miles then River D is 2360 and River C is 3160
Find the area of the circle then, multiply that by the height of the cylinder.
Area of a circle = PI x r^2
Area = PI x 8^2 = 64PI
Volume = 64PI x 11 = 704PI in^3
The greatest common factor of 64 and 96 is... uhh... hmm... 32! Because 64/32 is 2, and 96/32=3. 2 and 3 have no factors in common, except 1.
The answer is 32(2+3).
This means 32*2 + 32*3
this is the same as 64+96
